The center of a large upper level disturbance that brought widespread precipitation to the area over the weekend has moved into central Iowa . A cold front associated with this large system has moved offshore of the Texas Gulf Coast. Showers exited the WGRFC area of responsibility to the east this morning.

Today, there should be little precipitation chances in the WGRFC region due to upper level ridging. The exception is that light rainfall is possible in Deep South Texas and northeastern Mexico.

An upper level trough is forecast to reach California by mid-week. the effects of this system are expected to bring another round of widespread precipitation across Texas from Wednesday through Saturday morning with the heaviest amounts falling late Thursday night and Friday morning. This same storm system is also forecast to bring significant snowfall to the higher elevations in western and northern New Mexico Wednesday and Thursday.

...WGRFC Basins...
Current soil conditions remain damp over the eastern portion of Texas with states drying significantly westward. The forecasted rainfall over the next five days places precipitation over the saturated areas; however, currently the amounts are not heavy enough to create any flooding. The most sensitive areas are the headwaters of the Sabine and Neches as well as the central Trinity area. If rainfall amounts increase significantly above forecast only than will minor rises begin to occur. Otherwise no flooding is expected for the forecast period.
